For the first time, scientists may have found signals of dark matter. After analyzing reams of X-ray data, scientists in EPFL’s Laboratory of Particle Physics and Cosmology (LPPC) and Leiden University believe they could have identified the signal of a particle of dark matter. The substance, which was never observed, exists only as a theoretical cause for gravitational effects observed by…

Pulsars and black holes, two of the most enigmatic celestial bodies in the Universe may actually hold the key to understanding how Einstein’s theory of relativity and gravity interact. A pulsar is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. Pulsars are from when a star that turns becomes a supernova and then collapses into a neutron star;…

Organic molecules found on comet

The Philae lander found organic molecules on the surface of a comet.

As we were telling you already in several articles, the Rosetta probe is in orbit of a comet – the 67P/Churyumov-Gerasimenko comet. But to make things even more exciting, Philae, Rosetta’s lander, also made contact with the comet; among other things, the lander found carbon molecules on the comet – the basis of life on Earth. Considering how comets are believed to…

Study shows Dark Energy is erasing Dark Matter

dark matter

A newly published study has revealed that dark matter is being swallowed up by dark energy, offering valuable data not only about the nature and structure of these mysterious entities, but also about the future of the Universe. Dark Matter and Dark Energy In case you’re wondering, dark matter and dark energy are not Star Trek concepts – they’re real forms…

A group from the Laboratory of Astrophysics of Bordeaux, France, and the National Centre for Scientific Research (CNRS) has made a most exciting discovery. The astronomers found that an odd binary system – a solar system comprised of two stars – actually behaves like a double star, with two disks of matter encircling the system in a beautiful dance of gas and…

NASA’s Mars Curiosity Rover Arrives at Martian Mountain

14-245_1

It’s been a while since we’ve talked about the Curiosity rover, but that doesn’t mean that it stopped studying the Red Planet. Now, NASA’s rover has reached one of its main destinations: Mars’ Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission’s long-term prime destination. “Curiosity now will begin a new chapter from…

NASA confirms “Impossible” propellant-free microwave thruster works

emdrive-537x345

Designs for a device called a “microwave thruster” were proposed in 2006. While the device was physically sound and followed the principles of relativity, it has been dismissed by researchers who claimed that such a functioning device would defy the law of conservation of momentum. A team from NASA set out to trial the device and see if it works; lo and…

ESA’s billion-star surveyor, Gaia, ready to begin its science mission

Artistic representation of the ESA.

Gaia is an unmanned space observatory of the European Space Agency (ESA) which aims to catalog approximately 1 billion astronomical objects (mostly stars), about 1% of the Milky Way population. Gaia will provide a trove of valuable and spectacular data, including a precise three-dimensional map of astronomical objects throughout the Milky Way and map their motions. We were telling you…
